“Wow, Ted Cruz got booed off the stage, didn’t honour the pledge! I saw his speech two hours early but let him speak anyway. No big deal!” Trump tweeted.

Cruz earned the ire of the convention’s delegates — and, eventually, Trump — when he did not endorse the real-estate mogul during a primetime speech and told the crowd that it should vote its “conscience,” a not-so-subtle dig at Trump.

Cruz’s remarks, and the subsequent backlash, amounted to an extraordinary moment in a convention that was meant to attempt to unify the party ahead of a November general-election matchup with presumptive Democratic nominee Hillary Clinton.
